SPALT-DROPPlNG MECHANISM FOR SHINGLE-SAWING MACHINES.

SPECIFICATION forming part of Letters Patent No. 415,857, dated November 26, 1889.

Application filed July 27, 1889- Serial No. 318,970- (No model.)

T0 all whom it may concern:

Be it known that 1, FRANK CHALLONER, of Omro, in the county of \Vinnebago and State of \Visconsin, have invented certain new and useful Improvements in Spalt Dropping Mechanism for Shingle-Sawing Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to that class of shingle-machines in which a rotary bolt-carriage and a circular track with movable sections for dropping the spalts are employed. Its main object isto facilitate the discharge from the machine of the spalts or residuum of the bolts; and it consists, essentially, of mechanism under the control of the operator for effecting that end, hereinafterspecifically set forth, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure 1 is a side elet atiou of the spaltdropping mechanism in connection with mo vable sections, and Figs. 2 and 3 are respectively end and side elevations of the clutch for connecting and disconnecting the spaltdropping mechanism with suitable driving mechanism.

Referring to Fig. 1, L L represent movable sections of the curved track upon which the shingle-bolts rest when placed in the carriage.

They are supported at the upper ends of standards Z I, which are attached at their lower ends to rock-shafts M M, provided with inwardly-extending arms mm at right angles to said standards.

being shown by full lines in Figs. 1 and 3, and both indicated by dotted lines in Fig. 2.

A similar disk P is keyed upon the shaft a close to the disk 0, and is provided on opposite sides of said shaft with two sliding pins p p, parallel with said shaft n and having right-angled projections 13 p at their ends opposite the disk 0. The standards Z Z are drawn together and the track-sections L L are held in their normal positions byaspring I, attached at its ends to said standards.

A represents the central vertical shaft of the rotary carriage. It is provided with a bevel-gear Aiwhich engages with and drives a pinion n on the inner end of the shaft n.

R is a sliding rod supported in suitable bearings parallel with the shaft 71, and provided near its inner end with an arc-shaped arm 7' adjacent to and parallel with the inner face of the disk P in the line of travel of the inner ends of the sliding pins 1) 1). At its outer end said sliding rod R is connected with a foot -lever 'r,.fulcrumed to the frame of the machine. A spiral spring r placed around said sliding rod R and bearing at one end against one of its fixed supports and at the other against a collar 7' adjustably secured thereon, holds said arm 7' a short dis tance from the disk P.

S is a curved wedge-shaped guide supported next to the inner face of the disk P opposite the curved arm 0' in the line of travel of the projections p p on the sliding pins 1) p, as shown in Figs. 2 and 3. The disks 0 and P together constitute a clutch, by means of which the spalt-dropping mechanism is temporarily connected with the driving mechanism. The shaft 11 has an axial passage extending from one end and opening inside of the sleeve 0, and at its outer end communicates with an upwardly-bent tube 42?, through which oil is supplied to 1ubricate the bearing of said sleeve.

The residuum of each block, called the spalt, is discharged from the machine, when it passes over the movable sections L L of the track, by the operator depressing the lever 1-,which moves the arc-shaped arm 7" towards the disk P and thrusts one of the pins 13, which is adjacent to it, toward the disk 0 into engagement with one of the lugs 0 thereon. The cam o is thus caused to rotate in the direction indicated by the arrow in Fig. 2, and one of its elevations, passing under the rollers m, lifts the arms m m, throwing the upper ends of the standards Z Z and the sections attached thereto outwardly, so as to drop the spal'tthereon. As the projecting portion of the cam 0 leaves said rollers m, the spring Z draws the standards ZZ toward each other and returns the tracksections LL to their normal position. As the pin p in engagement with the lug 0 passes the inclined guide S in the latter half of its revolution, the projection 19 on said pin engages said guide and draws said pin out of engagement with the lug 0 thereby arresting the further rotation of said cam when the rollers m and the track-sections L L are in the position shown in Figs. 2 and 3. The

. cam 0 having two diametrically-opposite projections and the disks 0 and P being each provided with two lugs or pins, the proportion of the driving-gear A to the pinion n is as one-half the number of block-receptacles in the carriage is to one, so that the spalt-dropping mechanism may be operated and a spalt dropped from each block-receptacle in the carriage in succession.

I claim- 1. The combination, in a shingle-machine, with rock-shafts provided with standards to which are attached movable track-sections,

.and with inwardly-projecting arms, of a cam hearing at its periphery against the inner ends of said arms, driving mechanism, and a clutch arranged to connect and disconnect said cam with said driving mechanism, substantially as and for the purposes set forth.

:2. The combination, in a shingle-machine, with a rock-shaft provided with a standard to which is attached a movable track-section, and with an arm at right angles to said standard, of a cam bearing against the free end of said arm, a clutch arranged tov connect and disconnect said cam with suitable driving mechanism, and a lever arranged to throw said clutch into and out of gear, substantially as and for the purposes set forth.

3. The combination, in a shingle-machine, with movable track-sections supported upon standards fixed to parallel rock-shafts, and arms projecting inwardly from said rockshafts, of a cam bearing against the inner ends of said arms, a clutch consisting of two disks,

connecting said standards and arranged to return said track-sections, when released, to their normal position, inwardly-projecting arms fixed to said rock-shafts, a cam having a hearing at its periphery against the inner ends of said arms, a clutch consisting of two disks, one fixed to said cam and the other connected with driving mechanism and provided with two or more laterally-sliding pins which are arranged to engage with the disk fixed to said cam, an arc-shaped arm movable by the operator against the adjacent ends of said pins, and a Wedge placed opposite said arm and arranged to withdraw said pins from engagement with the other section of the clutch, substantially as and for the purposes set forth.

5. The combination, in a shingle-machine having a rotary carriage and circular track, of a laterally-movable track-section, a cam operating through suitable mechanism to temporarily remove said track-section from its ordinary position, a clutch arranged to connect said cam with driving mechanism, and a trip under control of the operator arranged to throw said clutch into and out of gear, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

FRANK CHALLONER.
